Ive narrowed it down to two kits for my 5.3 the difference is in the picture below which one looks to be the better kit plate or direct port/intake

 

How much are you planning on spraying? That helps weigh the decision alot.

Thinking the 150 maybe 200 which only the plate comes with the jetting for a 200 shot basically was wondering which is the better way to deliver the nitrous

 

Yeah, I'm not sure whose plate that is, but if you are only doing 150-200, the plate would be the more viable option for you. With a direct port, you get better cylinder to cylinder distribution, and the ability to tune or jet each cylinder individually, however the cost goes up significantly with a direct port, and you really only need them for higher horsepower applications. (300+ HP)

The plate will make for a simple, clean install, and it will do everything you need it to, and save you some money that way.

If you plan on spraying more than 200, our LS style plates (78mm, 90mm, and 102mm) do 50-400hp.
